Do not use methods which will modify the list after using Arrays.asList to convert array to list, otherwise methods like add/remove/clear will throw UnsupportedOperationException. 
<p>Examples:</p>
<pre>
    Positive example:
    List<String> t   = Arrays.asList("a","b","c");
    //warn
    t.add("22");
    //warn
    t.remove("22");
    //warn
    t.clear();

</pre>
